Every case of BSE is examined thoroughly by my Department to seek to ascertain the likely cause. In most of the cases, consumption of feeding stuffs has been shown. Prior to 1990 this would have invariably involved feed containing meat and bonemeal. Following the imposition of the ban on feeding meat and bonemeal to cattle in August, 1990, it is probable that a certain amount of feed containing meat and bonemeal remained on farms and some of this would have been fed to cattle. Additionally, testing of cattle feedingstuffs revealed the presence of meat and bonemeal, most likely caused by cross-contamination. In view of the foregoing and of the fact that there had been a significant number of cases of BSE in cattle which were born after the ban on feeding meat and bonemeal to cattle, I introduced regulations effective from 17 October last which are designed to strengthen controls on the manufacture, possession etc. of meat and bonemeal and to minimise the possibility of cross-contamination of cattle feed.
